it is so obvious that v$reqdist was desinged in Oracle 7 and nobody didn’t touch it and I think nobody will ever touch :) 0.04s? Not a big deal in 1995, but very long time for today :-)

I personally hate shared server and I’m very happy I has never been forced to use it in production system. We have system with 10 000 connected users using old-fashioned client-server architecture, but thanks to AIX OS we didn’t have to use shared server (SOLARIS or HP UX would have much more problems handling 10 000 processes).
